前些日子简单的使用 jacob 实现写数据到 MS Project，怕过些日子忘掉，所以整理了下，没有深入，只是简单的实现了下

Jacob 是Java-COM Bridge的缩写，它在Java与微软的COM组件之间构建一座桥梁

使用Jacob自带的DLL动态链接库，并通过JNI的方式实现了在Java平台上对COM程序的调用

Jacob操作ppt

使用 jacob 实现写数据到 MS Project

控制器

@PostMapping("/createMpp")

public String createMpp(@RequestBody JSONObject jsonParam) {

String fileName = (String)jsonParam.get("fileName");

if(fileName==null||fileName.equals("")) {

return "fileName is not null";

}

try {

Tasks dd = new Tasks();

Boolean rs = dd.create(fileName);

if(rs){

return "ok";

}

} catch (Exception e) {

e.printStackTrace();

}

return "error";

}

Tasks.java

package com.ppt.jacob.common;

import com.jacob.activeX.ActiveXComponent;

import com.jacob.com.Dispatch;

import com.jacob.com.Variant;

public class Tasks {

private static void setTaskValue(Dispatch task, TaskBean taskBean, int level) {

Dispatch.put(task, "Name", taskBean.getName());

Dispatch.put(task, "Duration", 1);

Dispatch.put(task, "Start", "2018年1月1日");

Dispatch.put(task, "Finish", "2018年3月1日");

Dispatch.put(task, "PercentWorkComplete", "11");

Dispatch.put(task, "OutlineLevel", level);

}

public boolean create(String fileName) {

ActiveXComponent app = null;

try {

app = new ActiveXComponent("MSProject.Application");

app.setProperty("Visible", new Variant(false));

Dispatch projects = app.getProperty("Projects").toDispatch();

//添加一个项目

Dispatch project = Dispatch.call(projects, "Add").toDispatch();

//生成一个task集合

Dispatch tasks = Dispatch.get(project, "Tasks").toDispatch();

for (int i = 0; i < 10; i++) {

Dispatch task = Dispatch.call(tasks, "Add").toDispatch();

TaskBean taskBean = TaskBean.builder().name("name" + i).build();

setTaskValue(task, taskBean, 1);

}

StringBuilder name = new StringBuilder("E:/test/");

name.append(fileName).append(".mpp");

Dispatch.invoke(project, "SaveAs", Dispatch.Method, new Object[]{name.toString(), new Variant(0)}, new int[1]);

} catch (Exception e) {

e.printStackTrace();

} finally {

if (app != null)

app.invoke("Quit", new Variant[]{});

}

return true;

}

}
